Reduced nitrogen oxide emissions from industrial vehicles ahead

Just a couple decades ago, nitrogen oxide emissions routinely plagued cities' skies and their residents' lungs. These polluting reactive nitrogen oxide gases from the tailpipes of combustion-engine vehicles and machinery are often abbreviated as NOx. These emissions have, over the years, been substantially mitigated by cleaner combustion engine technologies and the implementation of exhaust aftertreatment such as selective catalytic reduction (SCR) of NOx.
